Clinical studies of red light therapy on arthritis

There are many clinical studies showing the effectiveness of red light therapy for treating arthritis. In a review article on rheumatology, some 18 papers were considered. All studies involved double-blind trials with photobiomodulation in chronic rheumatoid arthritis patients and reported significant improvement in both acute small joint inflammation and chronic pain (80% success rate in relieving pain).

A different study of 170 patients with rheumatoid arthritis using photobiomodulation showed pain attenuation (pain reduction) of up to 90%. Red light therapy also accounted for increased cellular rejuvenation and blood flow, which play an important role in improving joint and tissue health in arthritic hands. Photobiomodulation also showed additional soft/connective tissue benefits like decreased oxidative damage—which degenerates joints—and decreased inflammation.
